Sir Tom Hunter, chairman of the Scottish Business Awards, said on its website: "Leonardo is not only a famous actor, he is a pioneering environmentalist and committed philanthropist whose charitable work is making a global impact.

"To have him address our nation's premier businesses and entrepreneurs is incredibly exciting.

"That the Scottish Business Awards is the largest awards dinner of its kind in the whole of the UK says a lot about the strength and ambition of Scotland's entrepreneurial community, and 17 November is set to be another very special night."
